I didn't participate during November but I've been doing it during December, and while it's a very different way of journaling to me it is interesting.
However, I can't really say if I'm enjoying it overly much other than finding some quality time to sit and write a page of something everyday.
We'll see how it goes and I might update again if my feeling towards it have changed and if it's changed my perception of journaling at all.
Has anyone else ever done something like this? I know Susannah Conway does a Journal Your Life E-course which I would love to participate in if it wasn't for a lack of money.
